SIPI-ION-CHARGING MECHANISM.

7 Application filed May 15, 1912. Serial No. 697,361.

To all whom it may concern:

Be it known that I, HARVEY S. WrNsoR, a citizen of the United States,and a resident of the city of New York, Sheepshead Bay, borough ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Siphon-Charging Mechanism, of which the following is afull, clear, and exact description.

My invention relates generally to siphon charging mechanisms and, moreparticularly, it is directed to a construction embodying improvedfeatures, whereby siphons may be quickly and safely charged.

The principal object of my invention is to provide a siphon chargingmechanism embodying a substantial structure and a number of cooperatingparts, whereby siphons may be charged with a gas contained in a suitablecartridge in a quick and safe manner.

Other objects and advantages of the in-' vention, not particularly setforth at this time, will appear as the description thereof proceeds, itbeing noted that the parts set forth and described in the drawings aremerely typical and illustrative of what may be used to accomplish thepurpose of the invention, such parts being capable of various changes indesign and relation among themselves.

Reference is to be had to the accompanying drawing, forming part of thisspecification, and showing a vertical sectional view of a siphon withthe charging mechanism and the cartridge in operative position Anysuitable siphon 1 is provided with the usual interior tube 2 extendingto the valve contained in the head 3, the valve being operable throughthe handle 4:, the outlet being through the nozzle 5. The siphon, whenit is to be charged, is placed within the casing 6, preferably ofmetallic material, the lower inside portion of which is provided with anumber of resilient olfsets 7 against which the lower edge portion ofthe siphon is adapted to contact as the device is moved about, theseresilient offsets taking up any shock, due to movement of the siphonwithin the casing, whereby handling of the outfit is rendered more safe.The top of the casing is hemispherical and preferably made up of twosimilar parts 8, 9, pivoted to the main portion or casing 6 by means ofpins 10, the part 8 being provided with a strap 11 which extends there-Specification of Letters Patent.

around, the ends of which are separated and provided with openingsthrough which a movable pin 12 extends; the part 9 is pro-' vided withan offset or lug 13 having an opening-through which the said pin12extends, the two parts forming the hemispherical top of the casingbeing thereby held in engagement with each other with the siphonsecurely positioned within the casing.

Mo-vably carried on the outside of the casing 6 and normally supportedon the pin 14; carried by a portion of the before-mentioned lug oroffset 13' is the charging mechanism indicated as a whole by 15; theunder side thereof is provided with an opening 16 which extends aroundthe said pin 14, movement of the charging mechanism on the casing 6within certain limits being thereby permitted. One side of the casing 6is provided with a shelf or support 17 against which the lower portionof the charging mechanism rests, the mechanism being movable withrespect to the support or shelf 17, while in engagement therewith.

The charging mechanism 15 is made up of two parts; one of the parts isessentially a rectangular frame, having the sides 18 connected togetherby an end 19, the upper end of the frame being provided with atransversely extending pin 20 on which a handle or lever is pivotallymounted,this

lever comprising the handle end 21, the cam end 22, and the intermediatecurved portion 23, along opposite sides of which the spaced projections24 extend, the said projections being adapted to embrace the handle 4 ofthe valve of the siphon when the siphon is being charged, the under sideof the curved portion 23 of the lever engaging the said handle 4.

Slidably mounted between the sides 18 of the be-forementioned frame isthe head 25, provided with suitable offset guides 26, whereby it is heldin position between the said sides, this head being provided with aforwardly extending portion 27 andwith an offset 28 from which aforwardly extending pin 29 extends, the pin being encircled by a helicalspring 30; the under side of the forwardly extending portion 27 adjacentthe head 25 forms a pocket 31 adapted to receive and bear against theupper endof the head of the siphon in order to provide a suitablesupport when the charging is being accomplished, the said cam end. 22 oft the lever at the upper end of the charging mechanism engaging the saidhead 25 and bringing it closely adjacent the head of the siphon as thecurved intermediate portion of this same handle or lever engages theouter end of the handle 4 of the siphon valve in order to open the valveand maintain it in such position.

The second part of the charging mechanism 15 is made up of the valvularelement 32 mounted between the sides 18 of the beforementioned frame,the upper end of this element being provided with an arm 33, having anopening 34 therein through which. the said forwardly extending pin 29 ofthe: head 25 extends, one end of the said helical spring 30 bearingagainst the outer end of; this arm so that, when the said lever or.handle mounted on the pin 20 at the upper end of the movable frame, isout of engagement with the handle 4 of the siphon, the spring 30, byengagement with the said head 33 and the ofi'set 28 carried by themovable; head 25, will maintain the said handle in an elevated position,at the same time hold ing the two parts of the charging mechan1sm 1nfixed relation.

The lower end of the valvular element 32:

is provided with a chamber 35 in which is a springpressed hollow valverod 36, the spring being designated 37, the upper end of the springbearing against a screwthreaded plug 38, the said valve rod 36 beingprovided with an opening extending therethrough which communicates witha transversely extending chamber 39 within the valvular body; the outerend of this rod 36 is also provided with packing material 40 adapted toclosely engage the upper open end of the valve contained in thecartridge 41, it being noted that in the drawing the relation of theparts is such that the said rod 36 has been entered into the open end ofthe cartridge in order to open the said valve therein and permit the gasto pass through the opening in the rod, leakage being prevented by theengagement of the said packing material 40 with the peripheral portionof the upper end of the cartridge. Between the upper end of the saidopen valve rod 36 and the transversely extending chamber 39 in thevalvular element is a passageway 42. Adjacent the upper end of thevalvular member and contained within a chamber 43 is a plug 44, againstthe upper end of which a helical spring 45 bears, the end of thischamber being closed by a screw-threaded plug 46 contained with in aresilient washer 47 and having a passageway extending therethrough, theend 48 of the said plug 46 extending beyond the washer 4'7 and forming aprotuberance adapted to be extended into the open end of the nozzle 5 ofthe siphon when the same is being charged, as shown in Fig. 1; thischamber 43 in the valvular element communicates with the saidintermediate chamber 39 through the medium of the V-shaped passageway 48and a second passageway 49, the second passageway communicating with achamber 50, the said intermediate chamber 39 also communicating withthis chamber 50 through the medium of a valvecontrolled opening 51, theouter end of the said V-shaped passageway is closed by a removable plug52, while the lower end of the said intermediate chamber 42 is closedthrough the medium of a removable plug 53, both of which can be easilytaken out when it is desired to clean the chambers or passageways.Within the said intermediate chamber 39 is a movable valve comprising aspindle 54 having an enlarged end 55, the upper end of the spindleengaging a flexible washer 56, against which a helical spring 57engages, this spring being contained in a suitable cap 58 having anopening 59 through its upper end; the spring 57 nor mally maintains thevalve in this chamber in the position shown in the drawing. Should thepressure, however, of the gas in the cartridge 41 be excessive, suchpressure will close this valve against the tension of the spring 57,whereby such excessive pressure is prevented from being communicated tothe siphon. The stem of the valve is not of the same shape as theopening 51 through which the stem extends, the outside of the stem beingprovided with a number of cutaway portions forming channels throughwhich the gas normally passes.

Referring to the chamber 43 in the upper end of the valvular element, itwill be noted that the plug 44- normally closes one end of the V-shapedpassage 48 so that in the event of back pressure from the siphon afterthe siphon valve is open, such pressure will not carry over the chargeof water in the siphon into passageways and chambers described.

A cartridge is set. forth in the drawing, the structure of whichespecially adapts it for use as a medium of containing liquefied gasunder suitable pressure. the manner of disposing of the siphon-chargingoutfit being that a number of such cartridges may be used with onecharging mechanism so that, when the siphon becomes empty, it may beplaccdin the valve mechanism and the gas from a new cartridge enteredinto the siphon, whereby the water therein becomes charged. This siphoncomprises a substantially cylindrical metallic body 100 having asubstantially hemispherical bottom 10]., the bottom being preferablyintegral with the other portion of the body, whereby seams and jointsare avoided in order to provide for greater safety. The upper end of thebody 100 is constricted in order to form a neck 102, the neck receivingan interiorly threaded sleeve 103, which is preferably of brass, theupper end of the body tending therethrough,

being overturned, as at 104:, in order to engage the upper end of thesleeve and to provide a tight joint. The sleeve 103 is prevented fromturning with respect to the body or the neck of the cartridge by meansof inwardly extending protuberances formed in the body of the cartridgeswhich engage the sleeve, the sleeve being preferably of softer material.

Carried by the cartridge and in screwthreaded engagement within thesleeve 103 is a valve which comprises preferably the body member 105having a passageway 106 exthe upper end of the passageway terminating inan enlarged recess107; within the passageway 106 is the valve proper, aspindle 108, the upper end of the spindle being provided with an elementsuch as a screw 109 in engagement therewith, whereby the spindle isprevented from dropping into the cartridge when the same is emptied. Thelower end of the spindle is provided with a head 110, the upper portionof which is counterbored, as at 111, into which the narrow or lower endportion of the body member 105 engages, the parts being held in suchengagement by reason of the pressure within the cartridge, leakage beingthereby prevented. It will be noted that the side portions of the saidelement 109 at the upper end of the spindle 108 is provided withlongitudinally extending openings 112, whereby an outlet or inlet forthe gas is provided, the sides of the spindle 108 being also providedwith re-' moved portions or channels, or slots, through which the gasmay pass.

hen it is desired to charge a siphon of water, the siphon is placedwithin the easing 6 and the parts 8 and 9 are brought to closedposition, the cartridge 11 being placed at the'lower end of the frame ofthe charging mechanism and between the sides 18, the upper open end 107of the cartridge receiving the longitudinally extending valve rod 36which extends into the chamber 35 at the lower end of the valvularelement; the handle or lever, at the upper end of the chargingmechanism, is then turned about the pin 20 until the cam portion 22thereof engages the head 25, and the intermediate curved portion 23 0fthe handle or lever engages the end of the handle 1 of the siphon,whereby the valve of the siphon is opened. The movement of the handle orlever about the pin 20 causes movement of the frame portion of thecharging mechanism relatively to the valvular portion, the result beingthat the frame with the cartridge therein is moved against the saidvalve rod 36,

whereby the valve rod enters the cartridge and opens it, the gas thenhaving access through the chambers and passages described into the openend of the nozzle 5 of the siphon, and thence to the interior of thebottle. After the bottle has been charged, the handle or lever is againmoved about the pin 20 in order to close the valve of the siphon and tobring the open end of the nozzle 5 out of engagement with the projectingend 18 of the plug 46 at the outer end of the chamber 43, the backpressure of the siphon being prevented from' spreading through thechambers and passages by reason of the movable plug 14 within thischamber which engages the open end of the V-shaped passageway 48,thereby effectively closing 1t.

The mechanism herein described and claimed provides a simple andeflicient structure especially adapted for use in small places or foruse in the home, where it is inconvenient or impossible to obtain asupply of carbonated water from manufacturers, it being clear that thesize of the different parts and the material of which they are made,will depend largely upon the size of the siphons with which they are tobe used, as well as the pressures to be maintained in such siphons.

Having thus described my invention, 1 claim as new, and desire to secureby Letters Patent An apparatus of the class described, comprising thecombination of a receptacle for containing a siphon, a chargingmechanism adapted to carry a cartridge containing a compressed gas, thesaid charging mechanism comprising parts movable relatively one to theother, the said parts being spaced and adapted to form a pocket forreceiving the cartridge, one of the parts being provided with a hollowvalve rod for engaging the valve in the cartridge, means carried by thesame part and adapted to engage the spout of the siphon, the said partbeing provided with valves and passageways between the said hollow rodand the spout engaging means, and a device for moving said parts,whereby the hollow valve rod will move the valve of the cartridge,thereby placing the interior thereof in communication with the interiorof the siphon.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
